引入2-范数框架下的U-空间的概念,给出了2-范数框架下的U-空间的特征刻画,证明了这类空间具有一致正规结构和不动点性质.讨论了2-范数框架下的U-空间与其他凸性之间的关系,并得到2-范数框架下的U-空间的一些性质.
The concept of 2-normed type U-space is introduced.Characteristic of 2-normed type U-space is given.It is obtained that 2-normed type spaces have uniform normal structure and fixed point property.Also,the relationship between 2-normed type U-spaces and other convexity are discussed,some property of 2-normed type U-spaces are obtained.
